Abstract
The utility model discloses a novel screw rod spring stop mechanism. The problem of the unable initiative locking after the screw rod atress is solved. The structure is as follows: a novel spring stop mechanism comprises a screw rod, a fixed block, a positioning pin, a stop spring, a plane bearing, a rotating block, an upper friction plate, a lower friction plate, a fixed plate, a bearing and the like. When the screw rod is stressed to rotate, the screw rod spring stop mechanism completes the stop of the screw rod by utilizing the characteristic that the inner diameter of the spring can be changed by the stretching and the compression of the spring. The stop force of the screw spring stop mechanism is provided by the upper friction plate and the lower friction plate. And a plane bearing is arranged between the fixed block and the rotating block of the screw spring stop mechanism. The device has the characteristics of compact structure, convenience in installation, low manufacturing cost and the like.
Description
Technical Field
A novel screw spring stop mechanism belongs to the field of mechanical parts.
Background
The existing screw shaft can rotate normally when stressed after the displacement is limited at two ends, so that the screw cannot be stopped actively, and if a nut is matched with the screw, the nut can change position. Therefore, it is necessary to develop a screw active locking mechanism which has a simple structure, is convenient to install, can lock in time, and works stably and reliably.
Disclosure of Invention
In view of this, the utility model designs a simple structure, simple to operate, accessible time locking, job stabilization reliable screw rod spring stop mechanism.
The technical scheme of the utility model is that: a novel screw spring stop mechanism comprises a screw, a fixed block, a positioning pin, a stop spring, a plane bearing, a rotating block, an upper friction plate, a lower friction plate, a fixed plate, a bearing and the like.
Preferably, in the stop mechanism, the fixed block is connected with the screw rod through the positioning pin, and the fixed block rotates along with the screw rod when the screw rod rotates. The stop spring and the rotating block are in interference fit with the fixed block, so that the stop spring can be deformed in time to complete the stop when rotating.
Preferably, the lower friction plate is fixed to the fixing plate, so that a friction stopping force can be generated in time.
Preferably, a plane bearing is arranged between the fixed block and the rotating block so as to transmit the rotating moment in time.
Compared with the prior art, the utility model has the advantages of: the stopping mechanism is provided with an upper friction plate and a lower friction plate, if the friction plates are excessively worn, the friction plates can be replaced without replacing the whole set of product, the later maintenance is convenient, and the cost is low; the whole body only has a mechanical structure, so that the working is stable and reliable; the friction coefficient of the friction plate can be adjusted according to the stress of the screw, so that the stress requirements of different customers can be met, and the production and batch are convenient and quick.

Fig. 1 is a schematic structural diagram of the present invention.
Wherein: 1-screw rod, 2-fixed block, 3-locating pin, 4-stop spring, 5-turning block, 6-plane bearing, 7-upper friction plate, 8-lower friction plate, 9-fixed plate and 10-bearing.
Detailed Description
As shown in the figure, a novel screw spring stop mechanism is characterized in that: a novel spring stop mechanism comprises a screw rod, a fixed block, a positioning pin, a stop spring, a plane bearing, a rotating block, an upper friction plate, a lower friction plate, a fixed plate, a bearing and the like. According to the principle of simple structure, convenient installation, timely stopping and stable and reliable work, a screw rod 1 and a fixed block 2 are assembled, a positioning pin 3 is inserted into the three parts to enable the three parts to have a whole stroke, a stopping spring 4 is inserted into the fixed block, a plane bearing 6 is placed into a rotating block 5, the rotating block 5 is inserted into the stopping spring 4, an upper friction plate 7 and a lower friction plate 8 are placed at the rear end of the screw rod 1 to enable the above parts to have a sub-assembly in the stroke, a bearing 10 is pressed into a fixed disc 9, the sub-assembly is inserted into a pressed bearing 10, and the upper end face of the screw rod 1 is fixed, so that the screw rod cannot have axial displacement and can only rotate. When the mechanism operates, when the screw rod 1 rotates clockwise, the stop spring 4 is compressed, the inner diameter is increased, no stop force exists, and the screw rod 1 can normally rotate; when the screw rod 1 rotates anticlockwise, the stop spring 4 stretches, the inner diameter is reduced, the spring 4 tightly holds the fixed block 2, and stop force is generated, so that the screw rod 1 cannot rotate.
